H. MoCULLnRs, a States, and a resident of Clayton, in the county of Johnston and State of North Carolina, have invented certain new and useful Improvements in aCornhinedOultiwater and Harrow; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l of the drawings Fig. 2 is a side view. Figs. tionai detail views.

This invention has relation to certain improvements in combined cnltivamrs and harrows; and it consists in the novelconstruction and combination of parts, as hereinafter specified.

in the accompanying drawings, illustrating the invention, the letter A designates a triangular frame, the converging side bars a a of which are connected by the transverse hare b and c. v

C is-a central longitudinal bar connecting" the transverse bars I) and c.

D is the draft-bar secured to one side of the center, the cultivator being what is known as a straddle-row.

E E are the handles, secured at their forward ends to either side of the draft-bar or to the bar 0 and supported by the brace F.

in each side hereof the frame are a series of harrovv-teethd, which gradually diminish in length from front to rear, the front tooth d on either side being bent or curved forwardly to present a raking-point,

Near the, rear end of each sidebar 0: is provided a bearing f; in which is jonrnaled one Be it known that I, WILL citizen of the United is a top plan view. 3, l, and 5 are sec- .end of a shaft H, the opposite end having hearings in aloloclr I, loosely mounted in the central longitudinal bar 40 of the frame.

(in each shaft is a dish J, having a smooth inner face and a GOEIVGX outer surface. This block is madeadjustaole longitudinally on said her by a setscrew 2', thereby providing shnztts heaving loose hearings for this purpose.

fer the lateral adjustment of the disks J, the

"'w tehit'is desired to use tWO .ings at one end in the side pieces on its shaft, substantially as specified.

Serial No. 31,918. (No model.)

The position of the shafts is such that the plants, as may be desired. Each disk is also made independentlyadjustable upon its Shaft by'a set-screw 7c or other suitable device. The shafts are held in the bearings f by the pivoted pieces or caps K, and by turning these to one side the said shafts and disks may-beentirely removed from the-frame and the device used as an'ordinaryharrow.

0n theforward end hook L, to which one trace mabe secured of fhcfina'chins with one animal, the other trace beingsecured to a similar hook on the other machine. The harrow-teeth may be made adjustable by means of the set-screws p, as shown.

Having thus described the invention, What Iclaini, and desire tosecure by Letters Patent, is-

1. in a cultivaton'the disks arranged one oneither side of the center and carried'by shafts having bearings at one end in the side pieces of the frame and at their other ends in an adjustable block,said shafts being removable from. their bearings and said disks independently adj ustableon the shafts, sobstantially as specified.

2. A combined cultivator prising the hshaped, frame, the side pieces of whichcarry harrow-teeth, the transverse frame-harsh and c, the central longitudinal plants on either 53 side, and by varying the adjustment thereof the soil may be set more or less toward the of the frame is a small bar (3, connecting said transverse bars, and-1 disks arranged one tel-and carried by shafts or axles having hea of the frame and at the other end in a bearing-block adj ustable on said center bar, and dreams for efifecting the independent adjustment of each disk In testimony whereof I afiix m i in presence of two witncsse WILL H. smoothness" Witnesses:
